Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of observation assistance, in particular to a new soft soil subgrade settlement observation plate. BACKGROUND

[0002] The subgrade settlement observation plate is a device for monitoring the settlement of the subgrade, which plays an important role in highway engineering construction. The subgrade settlement plate is usually composed of a settlement plate, a measuring rod, a sleeve, a protective cap, a measuring head, etc. The settlement plate is usually made of steel or concrete, and has a scale marked thereon for accurate measurement of the settlement height. The measuring rod and the sleeve are used to connect the settlement plate and the protective cap. The protective cap protects the measuring head and the measuring rod from damage. The measuring head is a device for reading the settlement height, usually with precise scales.

[0003] The existing patent (publication number: CN210741459U) discloses a new soft soil subgrade settlement observation plate, which belongs to the technical field of observation assistance. The new soft soil subgrade settlement observation plate comprises a base, two ground nails are arranged on the bottom of the base, a first section pipe is welded on the top of the base, a second section pipe is connected to the top of the first section pipe through a first sleeve, a third section pipe is connected to the top of the second section pipe through a second sleeve, and a sleeve head is sleeved on the top of the third section pipe. The new soft soil subgrade settlement observation plate not only has a reasonable structure, is convenient and safe to use, but also can assist in checking the layer thickness during the subgrade filling process, and is not easily affected by mechanical operation during the filling process.

[0004] However, the base of the above-mentioned device is large in size and inconvenient to store when not in use. In addition, the base needs to maintain a high level of horizontality with the road pit during use to ensure the perpendicularity of the measuring connecting pipe. The device often needs to use an external level multiple times for auxiliary measurement and comparison during installation, which is inconvenient to use. Practical new type

[0005] In view of the deficiencies of the prior art, the present application provides a new soft soil subgrade settlement observation plate, which has the advantages of convenient installation and storage, and solves the problems raised in the background art.

[0008] Each of the connecting assemblies comprises a connecting plate, a connecting rod, two sleeves and a pressing plate.

[0009] Through the above scheme, the two bottom plates can be stacked when idle, which can effectively reduce the occupied space. The connecting assembly and the limiting rod can realize the quick connection of the bottom plate and the connecting seat, effectively improving the convenience of the user. The first bubble level and the second bubble level can intuitively help the user determine whether the bottom plate is in a horizontal position when installing the bottom plate, effectively improving the installation efficiency and the convenience of the installer.

[0010] Further, each of the connecting plates is in sliding connection with the adjacent countersunk groove, the bottom end of each of the connecting rods is in fixed connection with the adjacent connecting plate, each of the connecting rods is in plug-in connection with the adjacent connecting hole, the inner wall of each of the sleeves is in threaded connection with the adjacent connecting rod, and the outer surface of each of the sleeves is in rotary connection with the adjacent pressing plate.

[0011] Through the above scheme, the connecting assembly can realize the connection of the two bottom plates.

[0012] Further, the upper surface of each of the pressing plates is fixedly provided with a first bubble level.

[0013] Through the above scheme, the first bubble level can detect the horizontal degree of the bottom plate in the transverse direction.

[0014] Further, the upper surface of each of the pressing plates is fixedly provided with a first bubble level.

[0015] Through the above scheme, the second bubble level can detect the vertical level of the bottom plate.

[0016] Further, the upper surface of each of the pressing plates is fixedly provided with a first bubble level.

[0017] Through the above scheme, the connecting measuring pipe can facilitate the user to obtain the roadbed settlement data.

[0018] Further, the top end of the connecting measuring pipe is provided with a measuring pipe top cap.

[0019] Through the above scheme, the measuring pipe top cap seals the pipe opening and protects the inside of the measuring pipe from external debris.

[0020] Further, the outer surface of each sleeve is knurled.

[0021] Through the above scheme, by knurling the outer surface of the sleeve, the friction coefficient can be increased, and the situation of the user's hand slipping can be slowed down.

[0022] Further, the outer surface of the connecting measuring pipe is galvanized.

[0023] Through the above scheme, by galvanizing the connecting measuring pipe, the corrosion resistance of the connecting measuring pipe can be improved, and its service life can be prolonged.

[0024] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0025] The novel soft soil subgrade settlement observation plate can realize the stacking of the two bottom plates when idle, effectively reducing the occupied space, and through the connection assembly and the limiting rod, the quick connection effect of the bottom plate and the connecting seat can be realized, effectively improving the convenience of the user, and through the first bubble level and the second bubble level, the user can intuitively judge whether the bottom plate is in a horizontal position when installing the bottom plate, effectively improving the installation efficiency and the convenience of the installer.
